Description

Technical Field

[0001] This invention relates to the field of molds, and more particularly to a high-precision product bending device with a precision micro-adjustment structure. Background Technology

[0002] Stamping machines are commonly used mechanical equipment in the metal processing field. Stamping machines are stamping equipment that uses molds to stamp materials into shape. Commonly used stamping equipment is divided into two main categories: mechanical presses and hydraulic presses. Mechanical presses are generally used. The selection of stamping equipment type depends on the nature of the stamping process, production batch, size and precision of the stamped parts. (1) For small and medium-sized blanking parts, bending parts or deep drawing parts, open mechanical presses are mainly used; (2) For large and medium-sized stamped parts, closed mechanical presses are mostly used; (3) For stamped parts produced in small batches, hydraulic presses or friction presses are mostly used; (4) For stamped parts produced in large batches, high-speed presses should be used as much as possible; (5) For stamped parts with complex shapes, multi-station automatic presses (CNC presses) can be used.

[0003] In stamping die technology, the bending process can only be completed with a single die; that is, one die can only correspond to one product. Due to process limitations, different products require different dies, which increases costs in various ways: design costs, intermediate transfer costs, machine usage costs, and die setup and debugging costs. It also reduces production efficiency and wastes manpower and resources. This has been a long-standing and very troublesome problem. Industry professionals have tried various methods to address these issues, but with little success. Summary of the Invention

[0004] The purpose of this invention is to provide a high-precision product bending device with a precision micro-adjustment structure to solve the problem that different products require different molds, which increases costs.

[0005] To achieve the above objectives, the present invention provides a high-precision product bending device with a precision fine-tuning structure, comprising:

[0006] Upper die mechanism, wherein a punch is provided on the upper die mechanism;

[0007] A lower die mechanism is located below the upper die mechanism, and a forming cavity is provided on the lower die mechanism, which is located below the punch.

[0015] As a further description of the above technical solution:

[0016] The connecting rod is provided with an elastic element, one end of which is connected to the moving insert and the other end of which is connected to the fixed insert.

[0017] As a further description of the above technical solution:

[0028] 1. In this invention, the upper insert assembly connects the punch to the upper mold mechanism. The upper insert assembly and the lower insert assembly have the same structure. By replacing or modifying the upper insert assembly, the distance between the two insert units can be adjusted, thereby fixing punches of different specifications to meet the production needs of different products. At the same time, the lower insert assembly is replaced or modified simultaneously to make the forming cavity match the size of the corresponding product.

[0029] 2. In this invention, by setting an electromagnet and a distance sensor in the insert unit, the distance sensor can detect the distance between the two moving inserts.

[0041] Please see Figure 1-3 This invention provides a high-precision product bending device with a precision fine-tuning structure, comprising:

[0042] Upper mold mechanism 1, wherein a punch 3 is provided on the upper mold mechanism 1;

[0043] The lower mold mechanism 2 is located below the upper mold mechanism 1, and the lower mold mechanism 2 is provided with a forming cavity 4, which is located below the punch 3;

[0044] The fine-tuning mechanism includes an upper insert assembly 5 and a lower insert assembly 6. The upper insert assembly 5 is disposed on the upper mold mechanism 1 and encloses the punch 3. The lower insert assembly is disposed on the lower mold mechanism 2, and the forming cavity 4 is disposed on the lower insert assembly 6.

[0045] The lower insert assembly 6 includes two insert units 61, which are symmetrically arranged. The gap between the two insert units 61 forms the molding cavity 4. Each insert unit 61 includes a fixed insert 611 and a movable insert 612. The fixed insert 611 is fixedly connected to the lower mold mechanism 2, and the movable insert 612 is movably connected to one side of the fixed insert 611.

[0046] The lower insert assembly and the upper insert assembly are arranged symmetrically, and the lower insert assembly and the upper insert assembly have the same structure. By adjusting the distance between the moving insert and the fixed insert, the spacing between the insert units can be adjusted.

[0047] The movable insert 612 has a sliding groove 7, a slider 8 is disposed within the sliding groove 7, and a connecting rod 9 is disposed on the slider 8. The connecting rod 9 is connected to the fixed insert 611. An electromagnet 17 is disposed within the movable insert 612. A distance sensor is disposed within the movable insert. The distance sensor is one of an optical distance sensor, an infrared distance sensor, or an ultrasonic distance sensor.

[0048] The distance sensor can detect the distance between two moving inserts. When the distance between the two moving inserts changes, energizing the two electromagnets will generate a magnetic force. When the distance between the two moving inserts needs to be reduced, the two electromagnets are connected to current to generate a magnetic force that attracts each other, causing the moving inserts to attract closer to each other. When the distance between the two moving inserts needs to be increased, the two electromagnets are connected to current to generate a magnetic force that repels each other, causing the moving inserts to repel each other and move away from each other. This achieves the purpose of adjusting the distance between the moving inserts.

[0049] An elastic element 10 is provided on the connecting rod 9. One end of the elastic element 10 is connected to the movable insert 612, and the other end is connected to the fixed insert 611. The elastic element 10 is a spring.

[0050] The fixed insert 611 is provided with a screw hole 14, and a bolt 15 is provided in the screw hole 14. The bolt 15 passes through the screw hole 14 and is connected to the lower mold mechanism 2. This facilitates the installation and disassembly of the fixed insert and reduces the assembly difficulty of the fixed insert.

[0051] The upper mold mechanism 1 includes an upper mold base 11, a clamping plate 12 and a stripper plate 13. The clamping plate 12 is connected to the bottom of the upper mold base 11, and the stripper plate 13 is connected to the bottom of the clamping plate 12. The clamping plate 12 covers the upper insert assembly 5.

[0052] The lower mold mechanism 2 includes a lower mold base 21 and a lower template 22 disposed on the lower mold base 21, and the lower insert assembly 6 is disposed on the lower template.

[0053] The lower mold base 21 is provided with a through hole 16, which penetrates the lower mold base 21 and is located directly below the molding cavity 4. The through hole facilitates the discharge of waste material and prevents waste material from accumulating on the mold.

[0054] Working Principle: The upper insert assembly connects the punch to the upper die mechanism. The upper and lower insert assemblies have identical structures. By replacing or modifying the upper insert assembly, the distance between the two insert units can be adjusted, allowing for the fixing of punches of different specifications to meet the production needs of different products. Simultaneously, the lower insert assembly can be replaced or modified to match the size of the corresponding product. Electromagnets and distance sensors are installed within the insert units. The distance sensor detects the distance between the two moving inserts. When the distance between the two moving inserts changes, energizing the two electromagnets causes the punch to... Electromagnets generate magnetic force, causing two magnets to attract or repel each other, thereby adjusting the distance between the moving inserts and, consequently, the size of the forming cavity. Precise adjustment can be achieved by controlling the current. After the product is processed, the moving inserts can be moved apart by a certain distance to facilitate product unloading, and then returned to the set distance. During product processing, a distance sensor can detect the size of the forming cavity in real time, and the sensor feeds back the detected information to the electromagnet, allowing the electromagnet to be energized and adjusted accordingly, thus improving the processing quality of the product.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
